General Electric GE4
Template:Short description Template:Infobox aero engine
The General Electric GE4 turbojet engine was designed in the late 1960s as the powerplant for the Boeing 2707 supersonic transport.[1][2] The GE4 was a nine-stage, single-shaft, axial-flow turbojet based largely on the General Electric YJ93 which powered the North American XB-70 bomber.[3] The GE4 was the most powerful engine of its era, producing Script error: No such module "convert". dry, and Script error: No such module "convert". with afterburner.[4] The Boeing 2707 was cancelled in 1971, putting an end to further work on the GE4.
